Get the answer daswilhelm a b à CPUs January 24, 2013 6:29:56 PM your cpu supports ddr3 up to 1066. you are trying to run 1600. only thing to check would be in the bios, make sure its set to run triple channel ram, not dual channel. kLa_89 January 24, 2013 6:33:19 PM I turned on X.M.P. in BIOS and memory is runing normal @ 1600MHz, except BIOS and Win dont see other 2 GB, so nothing is changed , overcloked or not... daswilhelm a b à CPUs January 24, 2013 6:41:10 PM does your bios give you an option on how many channels of ram to use? kLa_89 January 24, 2013 6:43:06 PM nope, i didnt see that option... daswilhelm a b à CPUs January 24, 2013 6:49:04 PM strange, there should be, i have setup 2 of those boards, maybe a different bios version, but i thought i remember seeing that option. kLa_89 January 24, 2013 6:49:59 PM will check again... ty kLa_89 January 24, 2013 7:07:11 PM there is no such option in BIOS... BIOS is ver. 0908... daswilhelm a b à CPUs January 24, 2013 7:09:05 PM in that case, since the ram speed doesnt match the cpu, and its not on the QVL, i would say thats most likely the wrong ram for your system. maybe try to check for a bios update, that would be all i could think of. kLa_89 January 24, 2013 7:36:55 PM found something here, but the problem is I don't now what to do in BIOS... time for some experimenting kLa_89 January 24, 2013 7:39:03 PM sorry for double posting i cannot edit my posts yet http://gskill.us/forum/showthread.php?t=5059 daswilhelm a b à CPUs January 24, 2013 7:39:49 PM good luck! kLa_89 January 24, 2013 7:47:34 PM I found full guide , hope this helps : http://i4memory.com/f54/asus-x58-6-12gb-memory-overclocking-detecting-less-memory-than-installed-19200 papakostaskostas January 28, 2013 3:41:17 PM hello, go to starup, press ''msconfig'' then ''advanced options'' to the upper right there is square that tells you how much ram will be your maximum...try this hope it helps kLa_89 January 28, 2013 9:35:40 PM papakostaskostas said:hello, go to starup, press ''msconfig'' then ''advanced options'' to the upper right there is square that tells you how much ram will be your maximum...try this hope it helps ty for ur answer, i looked there and this option is not ticked.... but i exchanged this RAM for another model because i just couldnt make it work....
